Hi, Im trying to make thumbnail and enlarged picture by
duplication.
What i tried was using duplication of thumbnail movieclip
which jpg image is loaded
However it seems not working as i intended,so I had to make
empty movieclip and loaded image again!!!

I am concerning that if I use new movieclip and loading the
image again..it means users have to download the same image twice.

Basically, I am trying to make a list of thumbnailed images
with enlarged picture popes up when mouse rolls over them

Is there any proper way to make it happen?
or duplication just doesnt work even thou movieclip is
already loaded with image?

1- MovieClip have some properties like duplicateMovieClip
that disapear when you load something into them. Basicly I can't
explain the real reason or all function or properties that does not
work after a load, but you found one of them. Here is how you can
fix that:

simple create your movieclip. Now create an empty clip
inside. You will load your JPG in the empty clip. This one can't be
duplicated, but you will be able to duplicate its parent. Like
that:
myMc.anEmptyClip.loadMovie("blabla.jpg");
myMc.duplicateMovieClip("theNameYouWant", levelNumYouWant);

That will works.

2- Also, the way you where going to do, works too. yes the
user will have to load it again, but it is already in the Browser
Cache. It means that will load quickly the second time and after
that. Bad side is more that you will doble the bandwidth of the
images loading on your site.

3- You ask if there is a proper way to do that, it depends on
how you build you application. A simple way sould be to enlarge the
movieClip itself when the mouse goes over and reset it to the
original size when the mouse out.

No, that will not work

You are partly right - if you create a nested clip and assign
properties
(such as an onPress handler) to the parent clip, you can then
load content
into the child without overwriting the parent's properties.
If you load an
image into the child and then duplicate the parent however,
the image in the
child clip *will not be duplicated*. Try it.

Again, partly right. Lets take it bit by bit:

> yes the user will have to

The movie will have to load it again, but will probably load
it from cache.

> Bad side is more that you will doble

Not so. If it's in the cache, it doesn't use any bandwidth at
all - that's
what caching means! A copy of the image is saved on the
user's local hard
drive, so no bandwidth needs to be used when loading from
cache.

Basically, for the *majority* of users, loaded images will be
cached (this
is dependent on browser settings, but most users will have
their browsers
set to cache). This means that after the first load,
subsequent loads of the
same image will be quick and carry no bandwidth overheads.

The real issue here is that dynamic content in movieClips,
such as loaded
images, swfs, or graphics created with the drawing API will
not duplicate
when the clip is duplicated/ The accepted work around used to
be simply to
reload the aimge. Now with Flash 8 though you can use the
BitmapData class
to grab a copy of the image and redraw it to the newly
created clip if you
so wish.

Ok, here it is.
Before I've post a reply, I've test it and my first solution
works great!

This part works:
------------------------------------------
simple create your movieclip. Now create an empty clip
inside. You will load your JPG in the empty clip. This one can't be
duplicated, but you will be able to duplicate its parent. Like
that:
myMc.anEmptyClip.loadMovie("blabla.jpg");
myMc.duplicateMovieClip("theNameYouWant", levelNumYouWant);
------------------------------------------

Test it before telling me that does not works please!

About the second way and the bandwidth, It will works too,
but I beleave when you tell that takes the images in the cache, and
does not take more bandwidth.

I've shown you mine, now you show me yours :) I'd love to see
an example of
a dynamically loaded image being duplicated....

Me too. From the help files:
If you used MovieClip.loadMovie() or the MovieClipLoader
class to load a movie clip, the contents of the SWF file are not
duplicated. This means that you cannot save bandwidth by loading a
JPEG, GIF, PNG, or SWF file and then duplicating the movie
clip.
